Chapter 3, Operating Overview
Compensating for TX and RX Measurement Path Loss
Compensating for TX and RX Measurement Path Loss
| The Software can compensate for losses (through cables, attenuators, couplers, | |
| and so forth) between the Test System and the base station for the best accuracy in | |
| average power and receiver measurements. The loss values are entered into the | |
| Configuration Information Menu and are saved to memory if the Save | |
| Info To Memory feature is used. | |
Requirements | You must know the following loss values: | |
| • The total loss (in dB) between the base station’s transmitter test port and the | |
|
| RF IN/OUT port of the PCS Interface. |
| • The total loss (in dB) between the RF IN/OUT port of the PCS Interface and the base | |
|
| station’s receiver test port. |
| These values should include losses through any cables, splitters, attenuators, and | |
| directional couplers used in your test setup. | |
Steps | 1 | From the main menu, select Configuration Information Menu. |
| 2 | Scroll to and select TX Measurement Path Loss and enter the loss between the |
|
| transmitter’s test port and the RF IN/OUT port of the PCS Interface. Once selected, you |
|
| can use the knob to scroll up and down in 1 dB increments or you may enter the value |
|
| directly using the DATA keys. Press ENTER or the knob when the correct value |
|
| appears in the inverse field. |
| 3 | Scroll to and select RX Measurement Path Loss and enter the total loss between |
|
| the PCS Interface’s RF IN/OUT port and the receiver’s test port. |
| 4 | To return to the main menu, press the Main Menu (k5) key. |
Notes | The loss values you entered in the steps above will not be saved unless you use the | |
| Save Info to Memory feature. See "Saving Configuration Information to | |
